This is on FreebSD:
    -r-xr-xr-x  1 root  wheel  753864 Feb 24  2004 /bin/sh
It's the real /bin/sh

This is on Linux:
    lrwxrwxrwx  1 root root 4 Oct 27  2004 /bin/sh -> bash
It's the real /bin/bash


On /bin/sh:
    $ [ "a" == "b" ] && echo hi
    [: a: unexpected operator
    $

On /bin/bash
    $ [ "a" == "b" ] && echo hi
    $


So yeah, bash understands that when you use ==, you mean = :-/
